This invention relates to roofing of that type commonly constructed of felt impregnated with asphalt and coated with a heavy asphalt on which are spread and partially embedded particles or granules of/slate or other suitable surfacing material which gives color to the roofingand adds toits weather..

and iireproong qualities. This roofing is of comparatively thin `material and unless special coloring or methods of laying lare resorted to, presents al flat, uninterestingl ap'- pearance, giving an unsubstantial and cheap eifect. One method of relieving thisfwlat appearance to some extent is by laying the roof in a series of. overlapping courses or strips, these strips being cut if desired at their lower edges to simulate the butts of shingles.

Another method which has been paroposed is to produce shadow effects by variously coloring the'material.A This.' may be done by rolling the granular surface material into the asphalt coating. while plastic to a greater extent-'where shadow effects are desired than at other places so that the asphalt flows between the surfacing particles, filling the inf terstices and becoming more or lessvisible n vilnpresslon rolls,form1ng'1n lowrelief a series of. tabs 4 separated by narrow depresthe surface depending 'on the ressure used.

Y As the asphalt is black this actlon causes the According to the present invention the sure in the manner above described.

' pear darker being somew roof toappeardarker at vthe portions sub-v jected to greater pressures, giving the effect of showing the same color as the rest of the material under less favorable light 4conditions. This rolling also produces a surface Aeffect in` low-relief, the ortions which'aplIiat depressed below the level of the 1lighter colored portions.

roofing is composed of overlying courses, the

- ,4 5 surface? level of the exposed portions being 'depressedsharply about the entire exposed margin ofthe overlying course and tapering l therefrom to its normal level. .This insures the raising of the exposed margins above the level of the adjacent underlying material and greatly enhances. the apparent thickness of,

the edge. This a pearance is further heightened. by the 'sha' ow eifect produced by the darker coloring effected by t e localized pres- I This construction makesv possible a much more marked appearance of substantialiconsible with this type of rooting.,

struction than has hitherto vbeen found' pos- Fora more complete understanding o futhiswthe adjacent course as 'shown in Fi ""invention, together with further and 3- and the depressions 5 underlie t e slots `advantageous details and combinations of.

parts, reference may be had to the accompanying drawings in which- Figure. 1 is a plan of a portion of .a roof constructed (according to this invention.

Figures 2 and 3 are sections on lines 2 2 is a section on line 5-5 of 'inwardly from the lower edge of the strip.

vSomewhat above the upper end of theslolts .3 the lower edge of a .succeeding overlying course is to .be positioned with its slots @staggering the rslots 3.. Definingv the position of* the edge of this overlying strip the surface of the strip v1 is impressed sharply asat a as by passing the strip under suitably. formed sions 5 corresponding in shape and size to the slots 3, assuming thatthe overlying strip is of the :same contour as strip l. This im# particles of coating material to show on the pear darker at the depressed portions and giving a desired shadow effect.

The depressed portion r1ses vgradually from ,1 5

ao surface thereof, this causing, the strip to appressed,the surface thereof being level with that of the tabs 2. '1A are superp d-iii over in Figure 3 2, and 3, the tabs 2 lof each overlyingcourse mating the relief portions 4 of theugderlying course so that the sharply s portions a offeach course are po-v ioned directly nextto the lower edge of res 2 plurality of such 'strips ying courses as shown 3. This causes the tabs 2 at their margins to be spaced above-the adjacent surface of the underlying course the amount to which this surface is depressed below the general' level of the strip. Each course also is thus clearly marked to show the position of a succeeding course which adds to the facility with which the roof may be laid.

Due to the fact that thenpper surface of the material is rough, the courses do not l lie closely superposed so that by this construction an apparent thickness of the shingle butts, caused 'by the thickness of -the tabs 2 added'to the relief of the portions 4, may be substaitally twice the thickness of the strip material without dangerously thinning the material at the depressed portions. While as herein shown the roofing is composed of strips, either extending continuously across the roof or in the form of shorter sections, it being common in the art to employ sections having four tab portions, the same idea might also be` exemplified with individual shingles, it being only necessary for the purpose of vthis invention vto depress the surface of the underlying course sharply about the margin of the overlying course and tapering gradually upward away from this margin, this depressed portion being shaded as above described to give an added shadow effect. It is also evident that the lower edge of material might be cut in any shape desired and that the edges of overlying courses might be of different shape or pattern if` desired.

Having thus described an embodiment of this invention it should be evident that many changes and modifications might be made4 therein without departing from its spirit or scope as defined by the appended claims.
